Abstract:

BACKGROUND: The patients undergoing lumbar discectomy have a higher risk of recurrence. There are many different ways of reoperation, but there are few studies on spine-pelvis sagittal morphology of patients with recurrent lumbar disc herniation.
OBJECTIVE: To compare the effect of discectomy and posterior lumbar interbody fusion on spine-pelvis sagittal morphology of patients with recurrent lumbar disc herniation.
METHODS: Sixty-one patients of recurrent lumbar disc herniation after discectomy were divided into discectomy group (n=30) and posterior lumbar interbody fusion group (n=31) according to the re-repair method. The height of intervertebral disc, lumbar lordosis and pelvic projection angle in the two groups before and after treatment were measured and compared based on standing spine lateral X-ray images.
RESULTS AND CONCLUSION: After treatment, the height of intervertebral disc, lumbar lordosis and pelvic projection angle of patients in discectomy group were not significantly changed compared with before treatment (P > 0.05). After treatment, the height of intervertebral disc, lumbar lordosis and pelvic projection angle of patients in posterior lumbar interbody fusion group were significantly increased compared with those before treatment (P < 0.05). Before treatment, there were no significant differences in the height of intervertebral disc, lumbar lordosis and pelvic projection angle between discectomy and posterior lumbar interbody fusion groups (P > 0.05).After treatment, the height of intervertebral disc, lumbar lordosis and pelvic pelvic projection angle were significantly increased in the posterior lumbar interbody fusion group compared with the discectomy group (P < 0.05). These results demonstrate that discectomy cannot significantly change the spine-pelvis sagittal morphology of patients subjected to re-operation, but compared with the discectomy treatment, posterior lumbar interbody fusion has a greater impact on spine-pelvis sagittal morphology of patients subjected to re-operation.
